Multiquip C3484400103 Urea Water Tank (JP) - OEM Replacement Part

The urea water tank (JP specification) stores and supplies Diesel Exhaust Fluid (DEF) for the Selective Catalytic Reduction (SCR) emissions system on Multiquip WhisperWatt™ super silent generators powered by ISUZU BQ-6WG1X Tier 4 diesel engines. This emissions-critical component maintains proper DEF supply to reduce NOx emissions and ensure regulatory compliance during generator operation.

This genuine JP-spec tank is engineered for the DCA400SSI series 320-400 kW industrial generators, designed to withstand continuous operation in demanding applications. The urea injection system is essential for meeting modern emissions standards—failure or contamination of the DEF tank can trigger engine derating or shutdown. Regular inspection of the tank, fill cap seal, and supply lines prevents crystallization and maintains optimal SCR system performance.

Compatible with the following Multiquip WhisperWatt™ generator models:

• DCA400SSI4F
• DCA400SSI4F3B
• DCA400SSI4F3PD
